What jar-file dependency do I add to resolve this import?
import jdocs.AbstractJavaTest;
It's imported in Akka's own example code (https://doc.akka.io/docs/akka/current/java/testing.html) yet after a lot of searching I can't find any mention of the actual jar dependency and the Akka documentation search function is so unhelpful that it claims there are no mentions of "jdocs.AbstractJavaTest" even when the code is on the screen in front of me.
Note that the following artifacts do not contain it:
'com.typesafe.akka:akka-actor_2.12:2.5.6'
'com.typesafe.akka:akka-testkit_2.12:2.5.3'
Thanks for any help you can give.
